Key facts: Prosper

  • Prosper's population rose from 9,423 in 2010 to 30,174 in 2020, so most homes here are recent.[1]
  • DFW fell to −2°F and spent 139 straight hours at or below freezing.[4]
  • New houses rarely flood.

Two-story plans

In Windsong Ranch and similar communities, primary suites and laundries often sit upstairs. Work out what room is below each one, because that room takes the damage.[2] An attic air handler's clogged condensate line is a common summer culprit.

Clay and the foundation

Blackland clay shrinks when dry and swells when wet, so moisture near foundations matters.[3] In Star Trail and Gentle Creek, irrigation lines, pool fill valves and blocked patio drains can each look like a plumbing leak. Find the source before drying anything.

February 2021

DFW fell to −2°F and spent 139 straight hours at or below freezing.[4] Attic-routed lines in newer homes were exposed. Know where your main shutoff is before the next one.

Flood claims recorded in Collin County

Prosper sits in Collin County. FEMA publishes every National Flood Insurance Program claim with personal details removed, which gives a plain record of where water has reached insured buildings here.

What the Prosper claim record shows

For Prosper homes, the local precedents are the events behind the most Collin County claims: Flooding (40 claims), Early Summer Storms (27 claims) and Early Summer Severe Storms (7 claims).

About 62% of claims with a recorded zone came from outside the high-risk A and V zones, so a moderate-risk label does not mean a Prosper home stays dry.

A newer Prosper home is not exempt: 70% of claims with a known build date involved homes built in 1975 or later.

Federal disaster history for Collin County

FEMA lists 20 federal declarations covering Collin County. The most common types are hurricane (5), severe storm (4) and fire (3). The latest are Severe Storms, Straight-Line Winds, Tornadoes, and Flooding in 2024, Severe Winter Storms in 2021 and Severe Winter Storm in 2021. Federal aid can open after a declaration, so Prosper owners should look it up before discarding damaged items.

Prosper home checklist from these records

  • Don't rely on recent quiet years. Only 36% of Collin County claims date from 2015 or later, so older floods still show what can happen.
  • Insulate exposed pipes before 3-plus hard-freeze nights arrive, and know your main shutoff.
  • Test any sump pump before May, since Prosper averages 14 days a year with an inch or more.
  • Clear the air conditioner drain line before the 77 days of 90°F heat begin.
  • Keep dated photos of each room. After Flooding, 40 insured Collin County owners filed claims at about the same time.

What to tell the Prosper contractor

  • Your neighborhood
  • Which floor the leak is on
  • Whether the home has a pool or irrigation
